A vineyard has 145 acres of Chardonnay grapes. A particular soil supplement requires 5.50 grams for every square meter of vineya

SashulF [63]

3230 kilograms of the soil supplement are required for the entire vineyard

<h3>Further explanation</h3>

Some units that need to be recalled are as follows :

<em>1 km² = 247 acres</em>

Let's tackle the problem now!

A vineyard has 145 acres of Chardonnay grapes.

$145 ~ acres = \frac{145}{247} \times 1 ~ km^2$

$145 ~ acres = \frac{145}{247} ~ km^2$

$\boxed {145 ~ acres \approx 0.587 ~ km^2}$

A particular soil supplement requires 5.50 grams for every square meter of vineyard.

$1 ~ m^2 \rightarrow 5.50 ~ gram$

$1 ~ km^2 = 10^6 ~ m^2 \rightarrow 5.50 \times 10^6 ~ gram$

$1 ~ km^2 \rightarrow 5.50 \times 10^6 \times 10^{-3} ~ kg$

$\boxed {1 ~ km^2 \rightarrow 5.50 \times 10^3 ~ kg}$

$145 ~ acres = \frac{145}{247} ~ km^2 \rightarrow \frac{145}{247} \times 5.50 \times 10^3 ~ kg$

$145 ~ acres \rightarrow \frac{797500}{247} ~ kg$

$145 ~ acres \rightarrow 3230 ~ kg$

<h2>Conclusion :</h2>

It required 797500/247 kg ≈ 3230 kg of the soil supplement for the entire vineyard

What is the scale factor? ( the answer must be a fraction).

MrRissso [65]

Since these are similar triangles you can use any two corresponding sides to figure out the scale factor.

Use the bottom side. Going from the first triangle to the second the scale factor is:
15/9 = 5/3
